From my experience ( as an 18 stone 6'6" tower of sh1te ) I'd have to say the answer to your question is no, most definitely not ( keep reading, I had a happy ending ). For years I had...
this ( click on photos to make them huge )
...and this.
But I felt like this...
So I bought a 29er and it's...
LUSH! ( click on it again )
The Yos are the only bikes that came close to NOT looking like gates until you started staring at the tiny tiny wheels which looked daft. For anyone over 6'2" ish and
especially the very tall like us a 29er is a good way to go. For a start everything is in proportion; no vast headtubes, no tiny wheels, no scaffolding pole seatposts sticking out. Secondly there's the handling which is fantastic; just ignore the b*ll*cks written by short journalists getting legs over "
medium " sized 29er frames WHICH HANDLE LIKE BARGES ( really: they should only ever be made in sizes of 20" or over to make sense ). Thirdly there's the market; Americans ARE HUGE! Decades of good diet have made the average yank 9 feet tall and they're minted so there's a huge ( successful ) 29er market out there which means it'll last and there's spares, tyres and tubes aplenty. Finally there's the revenge factor! After years of finding out you're the wrong size and/or they don't make them that big you can finally turn round to all your
medium friends and say...
" Sorry mate, you're too bleedin' short. "
